A collection of six German alchemical treatises assembled by Johann Grasshoff and issued by the engraver-publisher Lucas Jennis at Frankfurt am Main in 1625 for students of the art. The plates are grids of small circular copper-engraved emblems, each ringed by a Latin motto and captioned with a philosopher's name, holding suns, furnaces, coupling figures, dragons and multi-headed busts in compact roundel frames.
